Documentation
Tests VNC on a remote machine, including logging in and taking a screen shot. It accepts a standard vnc credential file with which to authenticate.
The screenshot is a more realistic test that just a port test, and is done at minimum display quality leading it to be surprisingly fast test (~0.3 seconds).
The plugin relies on the vncsnapshot program.
On Gentoo: "emerge vncsnapshot"
On Debian: "apt-get install vncsnapshot"
or get vncsnapshot from http://vncsnapshot.sourceforge.net here
Usage
./check_vnc -H somemachine --passwd-file credentialsfile
OK: vnc logged in and image obtained successfully
./check_vnc -H Kosh --passwd-file vncpass --verbose
OK: vnc logged in and image obtained successfully. VNC server supports protocol version 3.8 (viewer 3.3)
./check_vnc -H Starfury -f vncpass --timing
OK: vnc logged in and image obtained successfully. Test completed in 0.307 seconds
Options
./check_vnc --help
usage: check_vnc options
options:
-h, --help show this help message and exit
-H SERVER, --server=SERVER
The Hostname or IP Address of the VNC server
-f PASSWDFILE, --passwd-file=PASSWDFILE
The VNC password file to use. You can generate this
using 'vncpasswd ' on the command line
-t TIMEOUT, --timeout=TIMEOUT
Sets a timeout after which the the plugin will self
1. Defaults to 10 seconds.
-T, --timing Enable timer output
-v, --verbose Verbose mode. Good for testing plugin. By default only
one result line is printed as per Nagios standards
-V, --version Print version number and exit
Limitation
Cannot currently test a vnc server on a non-standard port due to an underlying restriction of the vncsnapshot program which seems to be common to several vnc based programs. I have made a feature request for this, but until it is implemented, it's not possible to re-write this plugin to have a --port switch.

Works great! Not clear if the image is being saved permanently, temporary, or not at all. Still gets 5 stars though because it does exactly what I need it to do, and does it flawlessly.
